ROLLER-BLIND ADVERTISING DEVICE.

Application meg December 14, 1922. Serial No. 606,941.

To all whom it may concern.

Be it known that we, WILHELMUS HEN- DRIK LEi'rDEKKERs, a Dutch subject, and WILLIAM OLIVER RUDDLE, a British subject, both residing in London, England, have jointly invented certain new and useful Improvements in Roller-Blind Advertising Devices, of which the following is a specification.

Our invention relates to a roller blind advertising device, having a nest of rotating blinds which are unrolled in succession to display advertisements carried by the blinds.

The machine or device, placed in a case or frame which may be provided with a glazed front or face, is intended to display a number of advertisements, which fall one after another, at intervals, into a vertically disposed position in the front portion of the case, behind the glazed face if there be one, each advertisement, as it falls, covering the one preceding it.

The machine may be operated by the motion of a vehicle or conveyance upon which it is mounted, or by any other suitable means.

, to the outer face of the disc 0.

In order that our said invention may he understood, we append hereunto two sheets of drawings, illustrating an advertising device constructed according to the invention, and in which Fig. 1 is a fragmentary front elevation of the device.

Fig. 2 is a vertical section on the line a, a in Fig. 1, a portion ofthe frame being omitted for the sake of clearness, and

Fig. 8 is an elevational detail.

In the drawings, A denotes the case or frame which may be of any suitable construction and is here shown with an unglazed or open front and back. B is a horizontal rotatable shaft journalled in bearings B carried by the sides of the frame at their upper portions. C, C are two flat discs fixedly mounted on the shaft at a suitable distance apart.

Around the circumference of the discs are equidistant holes C in which run the spindles D of a number ofrollers D mounted between the discs in a manner to constitute a circular row. Each spindle D has at one end an extension D that passes through the adjacent flat disc 0' and carries a toothed pinion F The pinions F are fixed to the spindles D and are disposed in proximity The teeth of the pinions are arranged to mesh with corresponding teeth on a fixed toothed wheel or rack G carried by the support G attached to frame A in line with the axes of the disc C, C and shaft B.

The wheel has a gap or notch H, clearly shown in Figs. 1 and 3, made by the exclusion of a number of teeth, the position of the gap being in the same horizontal plane as the rotating shaft B and facing towards the front of the machine (see Fig. 1).

As the shaft and discs carrying the rollers rotate, the rollers also revolve between the discs owing to the engagement of the pinions.

F with the teeth of the fixed wheel G.

A sheet or blind I of paper or other flexible material bearing an advertisement is attached at one end in any suitable wayto each roller, and as the roller revolves in one direction between the discs, the paper is rolled up and at the same time carried around the axis of the shaft with the rotation of the discs. The free'end of each of the sheets I carries a weight U to assist the sheet in unrolling after the sheet has been rolled around a roller D. When the pinion on the roller becomes disengaged from the rack wheel on reaching the notch, the roller becomes free to revolve in a reverse or unrolling direction irrespective of the others that are still in mesh with the rack, whereupon theweight U attached to the sheet I falls and causes the sheet to unroll.

As the sheet or blind is of such a length that it does not become fully wound up on its roller when itspinion reaches the notch in the toothed rack, flat springs J are fixed to the top of the frame A in a manner to press on the sheet on the roller when it. is approaching the notch to prevent the weight from falling too soon and so partly overlap the preceding sheet already unwound and displayed. p v

For the purpose of causing the roller pinion F which at any moment is opposite the notch H to restart turning in the original or rolling up direction and .thusenable the teeth of the pinion to re-engage freely with those onthe rack, each pinion F is providedwith an arm K. The arm on a pinion opposite the notch, as the discs C, C revolve about the axis of the shaft B, will move into engagement with a stopV carried by the rack before the said pinion advances beyond the toothless notch and thereby cause the pinion, as the discs continuing to revolve, to make a slight turn in the rolling updirection before its teeth recngage with the rack teeth. 4

Motion is imparted to the horizontal rotating spindle B by means of a worm L on the end gof avertical spindle M that extends down the outside of the frame to the base The worm L engages a worm-wheel N car ried by a spindle X rotatably mounted on a bracket X fixed to the frame A, operating an eccentric W on the spindle On the eccentric isfmounted apawl O that is arranged to rotate ratchet wheel P containingas many teeth as there are rollers mounted between the discs; the ratchet being moi irted direct on to the rotating spindle B and the paw l being held in cooperative relatiori therewith by friction between the pawl and the eccentric vV.

Since the number of teeth in the ratchet wheel P is the-sameas the number of rollers, rollei, brought to the notch in the rack grl the completion of every downward stroke of the pawl 0 and one advertisen ient is unrolled or falls and occupies a position iii the front"part of the frame thereby displaying the advertisement thereon.

At the bottom of the vertical spindle M is fix ed spur wheel Q which is in gear with a pinion R'which in turn gears a pinion mounted on a spindle Y that can be rotated by means of a flexible cable S or any other suitable power transmission device operated by the movement of a vehicle or other actuating agent.

A ratchet wheel T is mounted .on the rot'ating spindle B, and is formed with a large numberof very fine teeth for co-operation with a pawl Z pivoted on the frame G" for preventing backward rotation of the discs C, C at anytime.

Having thus described the nature of the said inventionand the best means we know of carrying the same into practical effect, we claim l. A n'advertising device comprising in combination with a supporting frame, a shaft mounted therein a circular toothed rack fixed to the frame, said rack having acircumferentially disposed toothless notch,

a pair of flat circular discs spaced apart and fixed to the shaft, a number of'spindles arranged in a circular row between the discs,

the opposite ends of each spind lepivoted,re-.

spectively, on the two discs, a roller on each spindle, 'a, flexible advertisement-carrying blind attached at one end to each roller, a toothed pinion, fixedly mounted at one end of each spindle, the teeth of the pinions arranged to mesh with the teeth on the rack inorder to cause the rollers to travel around the rack and simultaneously rotate upon their axes-in a direction to roll the blinds thereon, ratchet gear mechanism for imparting a stepby-step rotary motion to the shaft and the roller-carrying discs, each pinion in turn being adapted to pass in front of the notch on the rack thereby passing out of mesh with the rack and permitting the corresponding roller to turn in the reverse rection toallow the blind rolled-thereon to unroll under the action of gravity, means comprising a shaft and worm-gear for actuatinp; said mechanism, and means for causing the said roller to re-start turning in the rolling-up directionand the teeth on its pinion to re-engage with the teethofthe rack.
